java - 如何抛出新的 ElementNotFoundException？

Question

int btnSize = driver.findElements(By.xpath("...")).size();

    List<WebElement> b = driver.findElements(By.xpath("..."));
} else if (btnSize == 1){
    WebElement b = driver.findElement(By.xpath("..."));
} else {

    //How do I throw an Exception (e.g. ElementNotFoundException)
    //these variants did not work?

    throw ElementNotFoundException;     
    throw (new ElementNotFoundException);
    throw (new ElementNotFoundException("not found"));
    throw (new ElementNotFoundException(Exception e));
}

当抛出一个新的异常时，基本上你通过调用它的构造函数来创建一个对象。所以它是
throw new ElementNotFoundException("not found"); 或
throw new ElementNotFoundException(exception)
其中异常是异常你咳嗽的对象 ;)
